Directions

Make the Polenta:
In a medium pot, melt butter and add the corn. Cook for 5–8 minutes, until the butter browns and corn becomes fragrant. Add 2 cups water and the milk. Bring to a low boil, then slowly whisk in the polenta. Cook, stirring continuously, for 3–5 minutes until thick and creamy. Stir in the parmesan, season with salt and pepper, then cover and let sit for 5 minutes. -
Cook the Shrimp:
While the polenta rests, heat olive oil and butter in a large skillet over medium heat. Add the shrimp, cajun seasoning, and black pepper. Sear the shrimp for 2–3 minutes on each side until just cooked through. Stir in garlic and thyme, cooking until fragrant, about 1 minute. Remove from heat and stir in lemon juice and chopped basil. -
Assemble:
Spoon the warm, creamy polenta into shallow bowls. Top with the shrimp and spoon over the buttery garlic-lemon pan sauce. Serve immediately.

Variations
-
Add veggies: Stir sautéed spinach, kale, or cherry tomatoes into the polenta for more nutrients.

-
Dairy-free option: Use olive oil and non-dairy milk for the polenta and shrimp.
-
Cheese swap: Try crumbled goat cheese or pecorino in place of parmesan.

Lighter version: Use cauliflower polenta or reduce the butter in both components.
Storage/Reheating
-
Storing: Store shrimp and polenta separately in airtight containers in the fridge for up to 3 days.
-
Reheating: Warm polenta on the stove with a splash of milk or water to restore its creaminess. Shrimp can be reheated gently in a skillet over low heat.
-
Freezing: Polenta freezes well. Shrimp is best enjoyed fresh, but can be frozen for up to 1 month.
FAQs
What kind of shrimp should I use?
Use large raw shrimp that are peeled and deveined. Fresh or frozen both work—just be sure to thaw frozen shrimp before cooking.
Can I use frozen corn instead of fresh?
Yes, frozen corn works perfectly when fresh isn’t available. Just thaw before adding to the butter.
Is polenta the same as grits?
Polenta and grits are similar but not identical. Polenta is usually made from yellow corn, while grits are made from white corn. You can substitute grits if needed.
Can I make this dish less spicy?
Yes, reduce or omit the cajun seasoning and sriracha (if used). You can use a milder seasoning blend or just garlic, salt, and pepper.
How do I know when shrimp are cooked?
Shrimp are done when they turn pink and curl into a C shape. Overcooked shrimp become rubbery, so watch closely.
What wine pairs well with this dish?
A crisp white wine like Sauvignon Blanc or Pinot Grigio pairs beautifully with the lemony shrimp and creamy polenta.
Can I make this ahead of time?
You can prepare the polenta and shrimp ahead, but for best texture, reheat gently and add fresh herbs just before serving.
Can I use instant polenta?
Yes, instant or quick-cooking polenta will cut down the cooking time even more. Follow the package instructions.
What can I use instead of cajun seasoning?
Try a mix of smoked paprika, garlic powder, onion powder, and a pinch of cayenne or chili powder.
Is this dish gluten-free?
Yes, this recipe is naturally gluten-free, but always double-check your seasoning blends and parmesan cheese labels.
